Phase shifting of neurological signals in a medical device system
First Claim
1. In a medical device system having a plurality of monitoring elements, a method for phase shifting neurological signals received from the monitoring element comprising the steps of:
- (a) receiving a first neurological signal from a first monitoring element and a second neurological signal from a second monitoring element;
(b) sampling the first and second neurological signals at different time instances resulting in a time shift between the first and second neurological signal samples; and
(c) time shifting signal samples of the second neurological signal to correct for the time shift so the second neurological signal is synchronized with the first neurological signal.

Abstract
Method and apparatus for phase shifting neurological signals received from monitoring elements of a medical device. The medical device comprises a plurality of monitoring elements each receiving a neurological signal. The device processes the neurological signals identify a time shift of the neurological signal relative to each other. The neurological signals are then time shifted according to the time shift upon which the signals are utilized to provide closed-loop feedback control of a treatment therapy.

8. A medical device system capable of phase shifting neurological signals to provide closed-loop therapeutic treatment of a nervous system disorder comprising in combination:
-
(a) at least one monitoring element, each generating a neurological signal of a sensed neurological condition;
(b) a therapy device providing treatment therapy to the patient in response to the sensed neurological condition; and
(c) computer executable instructions for performing the steps of (i) receiving a first neurological signal from a first monitoring element and a second neurological signal from a second monitoring element;
(ii) sampling the first and second neurological signals are different time instances causing a time shift between the first and second neurological signals; and
(iii) time shifting signal samples of the second neurological signal so the second neurological signal is synchronized with the first neurological signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
